OK, here's the story. I have a K-Line A5 Switcher with TMCC that worked fine in both conventional and Command mode. I attempted adding the ERR Cruise Commander M module with partial success. By "partial", I mean the cruise worked while in forward, but the engine would no longer run in reverse. I returned the board to ERR and they confirmed the board was defective and they sent me a new board. I installed the original K-line motor driver board and discovered the A5 would no longer run in command mode. It was suggested that the R2LC board had gone bad. I purchased a new R2LC-08 board thinking this would cure all my problems. I installed the new R2LC board and discovered the engine will not run in conventional or command mode. I reinstalled the original R2LC board and the engine runs in conventional mode but not command mode. I have not attempted the cruise commander reinstall until I get things working again. Does anyone have a suggestion or fix? Thanks.
